It is well documented that pan trap color greatly influences arthropod catch composition. Additionally, it has been demonstrated that pan trapping catch varies with habitat. The goal of this study is to present preliminary data on pan trap yield from an imperiled ecosystem marked by high rates of endemicity, longleaf pine flatwoods. Yellow, blue, and white pan traps were evaluated in a section of longleaf pine flatwoods in June 2017 in central Florida, USA. A total of 360 arthropod specimens representing nine taxonomic orders were recovered, with 117 individuals from yellow traps, 125 from blue, and 118 from white. Contrary …

A Role For Intercept Traps In The Ambrosia Beetle (Coleoptera: Curculionidae: Scolytinae) Ipm Strategy At Ornamental Nurseries, C. T. Werle, B. J. Sampson, M. E. Reding
Midsouth Entomologist
Invasive ambrosia beetles (Coleoptera: Curculionidae: Scolytinae) cause significant damage to ornamental nursery tree crops throughout the eastern United States. Depending on surrounding habitat, some nurseries can undergo large influxes of ambrosia beetles from the forest to susceptible nursery stock. Ethanol-baited intercept traps are highly effective as monitoring tools that can capture large numbers of dispersing ambrosia beetles. Beetle trap captures at varying distances within nursery interiors were determined across replicated transects that either included or lacked a row of edge intercept traps. Although nearly 90% of ambrosia beetle captures were from the edge intercept traps, there was no significant difference …

Effect Of Coccidiodomycosis In Livestock, Robert Wood
Midsouth Entomologist
Coccidioidomycosis, also known as Valley Fever, is a fungal infection that affects most mammals. It is found throughout the semi-arid parts of the Americas. Valley Fever was first described in 1892 as a parasitic disease with high mortality and morbidity, but is now considered to be a low morbidity and mortality fungal disease. Although the disease could have long lasting effects that ultimately lead to death, likelihood of mortality is low. Additionally, morbidity is reduced with appropriate treatment.
Chikungunya: An Imminent Threat To The United States, Breanna Lyle
Chikungunya: An Imminent Threat To The United States, Breanna Lyle
Midsouth Entomologist
Recent years have seen a drastic increase in the number of cases of Chikungunya, a mosquito-vectored disease spread by day-feeding mosquitoes in the genus Aedes (Diptera: Culicidae). Cases of this disease have been on the rise in the Caribbean Islands as well as in many South American countries. The presence of the vector in many parts of the United States, as well as the proximity to these cases make Chikungunya a looming threat to the United States. While this disease is rarely considered a lethal one, the lasting impacts of an outbreak would be significantly detrimental to the infrastructure of …

Primary Amoebic Meningoencephalitis (Pam) - Deadly Waters, Morgan Hommel
Midsouth Entomologist
Naegleria fowleri Carter, is a protozoan that causes Primary Amoebic Meningoencephalitis (PAM). Naegleria fowleri is also referred to as the "brain-eating amoeba", due to the fact that it destroys the brain when in contact. PAM is an extremely rare, yet fatal disease. Fewer than 5 percent of people that have had PAM have survived. PAM is in the United States as well as in underdeveloped countries, most recently Pakistan. PAM is avoidable, as long as the contaminated water does not enter the nostrils.

This survey has been done annually in all participating states for at least the last 5 years and since 2004 in Mississippi. The 2015 survey represents 11.7 million soybean acres across the southern United States. Overall, stink bugs re-emerged as the most expensive pest in soybean followed closely by corn earworm and soybean looper. The proportion of fields planted with insecticide seed treatments decreased slightly for the second consecutive year to 60% of all acreage. …
Dengue Fever: Should We Be Concerned As Americans?, Shikinah D. Washington
Dengue Fever: Should We Be Concerned As Americans?, Shikinah D. Washington
Midsouth Entomologist
Dengue fever is a virus transmitted through mosquito bites. There are cases in many countries throughout the world that occur every few years. The disease does not kill many people, however, it can make the quality of life very poor and cause people to die who have underlying disease. There is no vaccine to prevent it, and it is a disease that we Americans should not take lightly. It is very possible for there to be an outbreak in the United States, therefore we need to all take precautions against it. An outbreak here or anywhere else in the world …

Ross River Virus Runs Rampant On The Gold Coast Of Australia, Brandon Gerhart
Ross River Virus Runs Rampant On The Gold Coast Of Australia, Brandon Gerhart
Midsouth Entomologist
The first outbreak of Ross River Virus (RRV) occurred in 1928 in South Wales, Australia. I reviewed RRV literature published between 2001 and 2015. The virus is carried by a mosquito and transmitted through a wallaby as its most common intermediate host. Researchers arrived at their findings by conducting extensive lab work on both mosquitos and humans. Signs and symptoms of RRV include joint inflammation, pain, fatigue, and muscle aches. It takes 3-21 days for symptoms to appear, with an average of 9 days. There is no cure to RRV, and there is no vaccine currently being developed. The best …
Antibody Titers To Bed Bug Salivary Proteins In Chickens From An Infested Broiler Breeder House, J. Goddard, J. S. Portugal, K. Maschek
Antibody Titers To Bed Bug Salivary Proteins In Chickens From An Infested Broiler Breeder House, J. Goddard, J. S. Portugal, K. Maschek
Midsouth Entomologist
Bed bugs (Hemiptera: Cimicidae) might be significant pests in poultry operations, especially in broiler breeder houses. In this study, chickens in breeder houses, known to be infested with bed bugs, demonstrated antibodies to bed bug salivary gland extract, while those not exposed to bed bugs, did not. Antibody titers ranged from 1:160 to 1:640. These results document for the first time that chickens in commercial production, when exposed to bed bug biting, produce antibody responses to proteins contained in bed bug saliva.

Cryptosporidium Parvum: Is It Invincible?, Caitlin Wonnacott
Midsouth Entomologist
Cryptosporidium is a coccidian protozoan parasite that can affect mammals, reptiles, and birds. A coccidian is a single-celled protozoan that affects the epithelial lining of the intestinal walls of hosts it parasitizes. This parasite has a unique life cycle and can withstand common measures of sterilization. The infective oocyte stage is resistant and hardy. It takes on two forms where each goes to different places within the host. Contamination of water sources has led to large outbreaks of cryptosporidiosis, even though the water met and passed the standards for drinking water. Conclusions from previous studies will help lead the way …

What Is Leishmaniasis?, Kimberly Wilson
Midsouth Entomologist
Leishmaniasis is a parasitic disease that can cause painful sores to cover one's body. It is found in parts of the tropics, subtropics, and southern Europe. Leishmaniasis is caused by infection with a complex of protozoan organisms, Leishmania spp, which are spread by the bite of infected phlebotomine sand flies (Diptera: Psychodidae). There are several different forms of leishmaniasis in people. The most common are cutaneous and visceral. The cutaneous type causes skin sores. The visceral type affects internal organs like the spleen, liver, and sometimes bone marrow.

The George H. Bradley Black Fly Papers (Diptera: Simuliidae), T. M. Nations, K. T. Edwards, J. Goddard
Midsouth Entomologist
Dr. George H. Bradley, a former USDA and Army entomologist, conducted research on a variety of medically important insects during his career; most notably mosquitoes (Diptera: Culicidae) and black flies (Diptera: Simuliidae). Much of Dr. Bradley’s personal library was donated to the Mississippi Entomological Museum at Mississippi State University after his death. Six of Dr. Bradley’s papers in that library, apparently never published, were discovered concerning the ecology and biology of the southern buffalo gnat, which he called Eusimulium pecuarum, (now known as Cnephia pecuarum). These unpublished works provide much needed and never before seen information on this medically important …

Effect Of Chemical Cues On The Foraging And Tunneling Behavior Of Formosan Subterranean Termites (Isoptera: Rhinotermitidae), M. L. Cornelius, W. L. Osbrink
Midsouth Entomologist
Wood rot fungi can cause directional tunneling, aggregation behavior and increased wood consumption by subterranean termites. Because vanillin and guaiacol are byproducts of lignin degradation, these chemicals were tested as potential attractants to Formosan subterranean termites, Coptotermes formosanus Shiraki (Isoptera: Rhinotermitidae). In tunneling tests, termites tunneled faster in sand treated with vanillin, but not guaiacol, compared with control sand. Termite responses to vanillin were compared to two other chemicals that had been previously shown to affect bait discovery in field tests, Summon Preferred Food Source™ and a sports drink. When discovery of bait tubes was monitored in a foraging arena, …

Laboratory Assays With Various Insecticides Against Bed Bugs Taken From A Poultry House In Mississippi, J. Goddard, K. Maschek
Midsouth Entomologist
Bed bugs may be severe pests in poultry houses, especially broiler breeder houses, leading to stress, anemia, and lowered egg production in the birds. Insecticides are important tools in managing these pests; however, efficacy data for many commercially available products is lacking. This laboratory study evaluated 8 insecticides (5 traditional residual products and 3 natural or “green” products) against bed bugs collected from a poultry house in Mississippi during August 2014. Invader® (propoxur), Ravap® (rabon and vapona), and Cimexa® (silica gel) killed 100% of bed bugs when exposed to ceramic tiles sprayed with the products 24 hours earlier. Interestingly, Ravap®(rabon/vapona …
Description Of The Queen Caste Of Pheidole Obscurithorax (Hymenoptera: Formicidae), J. A. Macgown
Description Of The Queen Caste Of Pheidole Obscurithorax (Hymenoptera: Formicidae), J. A. Macgown
Midsouth Entomologist
Pheidole obscurithorax, the South-American big-headed ant, is native to South America, but now common along the United States Gulf Coast region. Although the major and minor workers castes have been described, reproductive castes have not. The spread of exotic and potentially invasive ant species that disperse by flight can be monitored in part through the use of various aerial and light traps. However, due to a paucity of descriptions of reproductive castes of ants in general, identifications of these castes from traps are difficult at best. To better facilitate the identification of P. obscurithorax and its spread in the Gulf …

Filth flies (Diptera: Muscidae), such as those that breed in feces and other organic refuse, have been documented as being mechanical vectors of pathogenic bacteria including E. coli O157:H7, that cause hemorrhagic colitis in humans, and Campylobacter spp., which is the principal causative agent of human enteritis. Recently, a molecular diagnostic technique has been developed to identify filth flies that have been exposed to bacterial pathogens using PCR of insect DNA. We used this molecular diagnostic technique to screen over 5,000 adult filth flies for Campylobacter spp. and E. coli O157:H7 from two Arkansas turkey facilities during 2002 and 2003. …
